' Application filed July 2a, 1924. SerialNo. 728,460.

To all whom it may concern/.-

' Be it known that I,.JoHN D. BRADY, a citizen .of the United States, residing at Bartlesville, in the county of Washington and State of Oklahoma, have invented certain new and useful Improvements in a Traveling Valve, of which the following is a specification. i

This invention relates to improvements in well pumping e uipment.

The :primary ob ect of this invention is i the provision of animproved plu nger or f men-t of wells. I

and important object of thispiston arrangementfor the pumping equip- A' further invention is the provision of a traveling valve for well pumping equipment includ-' ing'novel means .for maintaining plunger .cups and rings on the v plunger barrel, and to maintain the valve part in effective work- .A further object of this inventionis the provision of;an improved traveling .valve and :piston construction for the pumpingequipment of oil wells and the like, em-

. 'bodyingf-an assemblage of. parts which are locked in positive and effective manner, and

. whi ch cannot become detached, as is sometimes the casewith conventional plunger or piston-arrangement, very often resulting in oss of parts and pl gmg of wells.

A further object 0 this invention is the provision of a traveling valve for the pump 111g equipment of oil wells and the like, embodying a novel nut lock arrangement for maintaining thefparts of the traveling valve in' assembled relation, so that the same cannot rotate or move with respect to each other, and thus preventing possibility of detachment of parts incident to rotation of the valve in the working barrel. Otherob'ects and advantages of this .invention will be ap arent dun of the following etailed description.

In the drawing, wherein for the purpose of illustration is shown only a preferred embodiment of the improved valve, the letter, A may generally designate the improved traveling valve, piston, or plunger, which may; include the barrel B cup arrangement Fig. 5 is a plan view of a novel type of C;' follower D; nut E; crown F; and key G for connecting the partsof; the traveling valve against relative movement when in assembled relation. I

Referring to the barrel. B, the; same includes a cylindrical shaped body portion 10, '80

providin'g'an internal passageway 11 there'- through, with an externally smooth surface 12. At the lowerend of the body portion 10 a ':ircumferentially enlarged bottom head 14, is formed and provides a shoulder. 15 at the-juncture of the bod portion 10 with the a bottom head 14, exten in annularly about the external surface 12. his bottom head 14 is of the usual construction, andis integral with the body portion 10,havinglateral openings 16 therein communicating with the passageway 11 through the barrel B. At-its upper end the-barrel B is provided with an integral reduced portion. 18, which is externall I nally exten ing diametrically opposed slots or grooves 20 are provided inwardly of the external surface 12 of the body 10,at its upper end, having an outlet at their. upper the body portion 10 with the reduced portion 18. I

. The'cup arrangement C-includesthe-conventional fiber or flexiblecups 25, with the metal spacing rings or sleeves 26 Itherebetween; said cups and, rings being slipped screw threaded. Longitudiover the bod portion 10, from the reduced upper end 0 the barrel B, so that they-are held from slipping off the lower or bottom end of the barrel B because of the factthat the lowermost cup 25 engages against the through, upwardl annular shoulder 15 of the bottom head 14. These cups and rings are freely 'slidable along the body portion 10 of the barrel, to ermit their easy attachment and removal om said body portion, prior to the clamping of the same in their fixed relation thereon.

The follower D is preferably of ring shaped. formation, somewhat similar in appearance to one of the spacing rin 26, and it includes the reduced lower portion 28 adapted to fit in the uppermost cup 25 in the same manner as one, of the spacing rings 26. The upper enlarged portion 29 of the follower ispreferablyprovided with the substantially diametrically opposed notches 30 inwardly of the top edge 31 thereof, and a'portion of this top edge 31 provides an internal beveled seat 33 against which the nut E may engage, as will be subsequently described. As an important feature of the follower D, the same is provided with diametrically disposed pins 35, fixed in any approved manner in the follower portion "29, so that the inner end portions 36 thereof extend inwardly of the inside periphery of the passageway 38 through the follower D, and so that these ends 36-will slidably en age in the slots or grooves 20 of V the barrel when the follower Dis slipped into position over the barrel In this manner the follower may move longitudinally of the barrel, but is prevented from rota tional movement thereon, and the importance of which featurej -subsequently appear.

The nut E. is preferabl "internally screw threaded, as at 40, for a 'us tment over the reduced externally screw t "'aded end 18 of the barrel B, and the lowerbeveled edge 41 thereof is adapted to engage. iagainst the beveled edge 33 of the followei 'D to clamp the latter .downupon ""the' "cupand ring arrangement Bto hold the'same fixed on the valve barrel. .Thianut E provides an external polygonal wrench en' agingstructure, preferably exagonahj and circumferentially of this hexagonal-,wrench engaging-structure a groove 42 isprovided, intersected byvertical slots- 43 through "each of the side faces of the nut." Integral with and con-- sidered asla "partof thenut'f the u standing] reduced portion 46,-; screw threaded. at .347, for w e nection of the crownF thereon; partion 46 provides a passageway "48 -there-- of the screwYthreaded passageway 40 an aligning therewith. 1

u The crown F includes the substantial] cyhndrical shaped body 50,-'provided--wil 1 x the longitudinal slots 51 therethrou'g ll,

tending to the passageway 53 through the;v

' crown, and the lower internal'screw threads 54' are provided for detachable threadirlihg When the crown F is screw threaded upon the nut E the same provides a valve cage within which the check ball K may reciprothe ,cable' or pumping string may be connected to the traveling valve A.

Referring to the locking key G, the same preferably includes a vertical, preferably straight portion 60, midway between the ends of which, and laterally of each side thereof, the segmental tongues or fingers 61.

and 62 extend in a concentric arrangement. The tongues 61 and 62 together provide a segment greater than 180. In position the tongues 61 and 62 are slipped in the nut groove 42, and snapped past the greatest diameter. of the nut in this groove 42, so that the resiliency of the tongues or fingers 61 and-62 maintain the key G in position on the nut. The upper and lower locking fingers 63 and 64 of the part60 of the key G extend through a'vertical groove- 43 in the nut E in which they are positioned, and the tip ends of-these fingers 63 and 64 respectivelyextend above and below the edges of the nut polygonal body forreception within recesses 65 and 30; the former recesses, 65 i being provided upwardly 66 ofthe valve crown F.

The assemblage ofparts will be apparent from the foregoing description. The fol- .lower" is',- of course, prevented from rotaof the lower edge tion'al movement upon the body of the barrel B, and'when the nut E has been clamped upon the barrel 'tofix the follower D' and the cup' and arrangement in a fixed relation,'the crown F may be adjusted on the upper externally screw threaded portion of the nut 'Efu'ntil the desired recess 6.5 aligns with the desired recess-30 in the upper edge of the follower D. Then by merely slipping the key G in the relation des'cribedandshown'inthe drawings, upon tirepolygonal portion of the nut E, the same w1ll lock the crown F to the follower D and to the nut E, and will absolutely lock the f follower nut; and crown or valve cage Jina relation'w'hich cannot be acci dentally altered. The fact that the tongues Qcumference of said grooveinsures thatthe key'cannot slipout of the relation in which it is shown in Figures l and 3 of the drawand 62 are resilient and engage the nut the groove 42 thereof for the major cir- I respectively.
